Binary (0-1) points in the feasible region (Ax<=b).

Binary (0-1) points in the feasible region (Ax<=b).

Usage

binaryPoints(A, b)

Arguments

A

Constraint matrix.

b

Right hand side.

Value

A data frame with all binary points inside the feasible region.

Note

Do a simple enumeration of all binary points. Will not work if ncol(A) large.
